"Despite getting treatment every day, I have not been cleared to practice or play in the Peach Bowl due to the hip injury I suffered in the last game," Bush wrote on Twitter. "Due to this injury, I have thought hard about my future in football. Having been injured I realize how fleeting this sport can be. It has always been a dream of mine to follow in my father's footsteps and play in the NFL.

"This injury has made me realize how important this goal is to me and my family. Therefore, I have decided to forgo my senior season and enter the 2019 NFL Draft."

A fixture of Michigan's defense the last two seasons, Bush earned consensus All-America honors as a junior this season and is considered a first-round pick by most NFL draft analysts.

"I really like Devin Bush. I have him somewhere in the middle of the first round, he's where the NFL is going to right now. A super athletic three-down player who can play different spots as a run and chase linebacker," NFL draft analyst Matt Miller told the Free Press last week. "The only thing that I could see hurting him is if he comes in and just bombs the measurements. If he has super short arms or something. But then again, everyone already knows he's sort of small. So it shouldn't get held against him too much."

The 5-foot-11, 233-pound Bush had a breakout campaign as a sophomore with 102 tackles (10 tackles for loss) and five sacks. He finishes the 2018 season with 80 tackles (9 1/2 for a loss) and five sacks.

A standout prospect from south Florida in the 2016 recruiting class, Bush was immediately put into Michigan's rotation as a true freshman that season and never left.

Michigan's defense ranked No. 3 nationally last season and is No. 1 this season. Bush was a big reason why.

Bush and Gary aren't the only Michigan juniors with decisions to make. U-M cornerbacks Lavert Hill and David Long are also viewed as possible NFL draft picks. Quarterback Shea Patterson, also a junior, has not yet made a decision about his future, though Patterson has said he'll play in the Peach Bowl.

The Wolverines will play Florida in the Peach Bowl on Dec. 29 in Atlanta.
